Abstract: Currently the soybean crop is affected by the white mold (Sclerotinia sclerotiorum). The disease can reduce the crop yield and quality and decrease the prices of agricultural lands. The aim of the current research was to assess epidemiology of white mold on soybean crop grown at Arapoti, PR, Brazil, utilizing data related to agricultural practices and local meteorological factors. The experiment was conducted in a naturally infested area. The soybean crop was sown on October 18th, 2011. The experimental design adopted herein was a randomized block in a factorial combination with 4 row spacings (0.35, 0.45, 0.60, 0.75 m) and 4 plant populations (150, 200, 250, 300 thousand plants per hectare) and 4 replications. The temporal analysis of the epidemic was evaluated using mathematical models, such as Logistics, Monomolecular and Gompertz, in order to determine the best model that described the progress of the disease as a function of local meteorological elements. For the incidence data it has been shown that both logistic and monomolecular models were those that were best fitted to the experimental data. For severity, the best model related to the experimental data was the logistic one. Either for incidence or for severity, air temperature was considered to be the environmental factor most affecting the progress of the disease. The variability in the apparent infection rates of white mold on soybean was not affected by different row spacings and plant populations; therefore, suggesting that macroclimatic variations prevailed in such a fashion to mitigate the effect of cultural practices adopted in the field.
The Physical Principles Elucidate Numerous Atmospheric Behaviors and Human-Induced Climatic Consequences  [PDF]

Abstract: The principles that govern the operation of an open and a closed evaporator are relevant for the understanding of the open and “closed” Earth’s atmospheric behaviors, and are thus described. In these greenhouses, the water is included, otherwise the heat and mass balances do not match. It is incorrect to consider the radiation as the only energy transfer factor for an atmospheric warming. Demonstrations show that when the greenhouse effect and the cloud cover increase, the evaporation and the wind naturally decrease. Researchers did not understand why reductions in surface solar radiation and pan evaporation have been simultaneous with increased air temperature, cloudiness and precipitation for the last decades. It is an error to state that the evaporation increases based solely on the water and/or air temperatures increase. Also, researchers did not comprehend why in the last 50 years the clouds and the precipitation increased while the evaporation decreased and they named such understanding as the “evaporation paradox”, while others “found” “the cause” violating the laws of thermodynamics, but more precipitation is naturally conciliatory with less evaporation. The same principle that increases the formation of clouds may cause less rainfall. Several measurements confirm the working principles of greenhouses described in this paper. The hydrological cycle is analyzed and it was also put in form of equation, which analyses have never been done before. The human influence alters the velocity of the natural cycles as well as the atmospheric heat and mass balances, and the evaporation has not been the only source for the cloud formation. It is demonstrated that the Earth’s greenhouse effect has increased in some places and this proof is not based only on temperatures.
Climate Changes: How the Atmosphere Really Works  [PDF]
Ernani Sartori
Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.54016
Abstract: Top concepts adopted by the current science on climate changes or atmospheric warming are not in agreement with the first principles of the physics. This paper presents a new understanding on the atmospheric behaviors. For example, the radiation is not the only factor that influences the air temperature, as the law of conservation of energy defines and as shown physically and mathematically in this article. The Sun is not the only heat source for the atmosphere because there is generation of heat at the Earth’s surface by human activities. It is also shown that the water vapor is not a null effect and that the water vapor cannot be removed from the atmosphere for air temperature, greenhouse effect and climate changes considerations, in contrast to the current literature beliefs. The “feedback” concept is unfounded and invalid. The literature also says that “water vapor increases as the Earth’s atmosphere warms”, but this is also incorrect. The above equivocated understanding is accompanied by another one which believes that more water evaporates if the air temperature increases, but it is not in this way. These demonstrations and other authors’ surveys showing that in the last decades the planet became wetter eliminate the literature concept that the water vapor does not have influence on the atmospheric warming/cooling. The conventional water cycle is related to the mass of water (mass of evaporation \"\" mass of precipitation) and then the physical and mathematical principles of the new hydrological cycle that includes the direct human influence are shown. The same is done for the carbon cycle. It is solved the problem on why the wind speed on Venus is very high above the cloud deck while it is stagnant below it, being this the same physical principle valid for the Earth’s cloud cover. In the atmosphere, all the corresponding principles are the same, only their amounts change. It is demonstrated that the CO2 is not decisive for building and changing the temperatures of Venus, Mars, Mercury, Jupiter and Earth. Ice cores are not valid for “determining” “past” temperatures of the planet, because the mass of their air bubbles may be old, but the corresponding temperatures are not.

Abstract: in this paper the determination of acetylsalicylic acid (asa) in pharmaceutical formulations using square-wave voltammetry (swv) and a boron-doped diamond electrode (bdd) is described. by this proposed method, asa is directly determined in a 0.01 mol l-1 h2so4 solution without the need of a previous time-consuming alkaline hydrolysis step. a single oxidation peak at a potential of 1.97 v vs. ag/agcl (3.0 mol l-1 kcl) with the characteristics of an irreversible reaction was obtained. the obtained analytical curve is linear in the asa concentration range 2.50 × 10-6-1.05 × 10-4 mol l-1, with a detection limit of 2.0 μmol l-1. the obtained relative standard deviation was smaller than 1.4% for a 45 μmol l-1 asa solution (n = 10). the proposed method was applied with success in the determination of asa in several pharmaceutical formulations; the obtained results were in close agreement, at a 95% confidence level, with those obtained using an official method of the british pharmacopoeia.

Abstract: Despite the advances in the understanding of neural and genetic foundations of violence, the investigation of the biological bases of a mental disorder is rarely included in psychiatric evaluation of mental insanity. Here we report on a case in which cognitive neuroscience and behavioral genetics methods were applied to a psychiatric forensic evaluation conducted on a young woman, J.F., tried for a violent and impulsive murder. The defendant had a history of multidrug and alcohol abuse and non-forensic clinical evaluation concluded for a diagnosis of borderline personality disorder. We analyzed the defendant’s brain structure in order to underlie possible brain structural abnormalities associated with pathological impulsivity. Voxel-based morphometry indexed a reduced gray matter volume in the left prefrontal cortex, in a region specifically associated with response inhibition. Furthermore, J.F.’s DNA was genotyped in order to identify genetic polymorphisms associated with various forms of violence and impulsive behavior. Five polymorphisms that are known to be associated with impulsivity, violence, and other severe psychiatric illnesses were identified in J.F.’s DNA. Taken together, these data provided evidence for the biological correlates of a mental disorder characterized by high impulsivity and aggressive tendencies. Our claim is that the use of neuroscience and behavioral genetics do not change the rationale underlying the determination of criminal liability, which must be based on a causal link between the mental disorder and the crime. Rather, their use is crucial in providing objective data on the biological bases of a defendant’s mental disorder.

Abstract: although menarche is a late event in the puberal process, most parents do not realize until this moment that their daughters are no longer children. at that time, they usually turn to the pediatrician for enlightenment and serenity. they frequently ask about the girl's growth potential and for an estimate of her final height. there are only a few studies in the scientific literature on postmenarcheal growth, perhaps due to the special characteristics of adolescence, which makes interpretation of the results difficult. the purpose of this review is to provide pediatricians with a means of making more accurate prognosis than populational means on growth after menarche for the adolescent girl, taking into account she has already had menarche. there is no correlation between age at the peak of height velocity and final height. at menarche the adolescent has already reached 95.5% of her final height. progressively smaller increments in stature continue for 3 to 4.8 years. the early matures (menarche earlier than the mean age of 12.6 years) probably will grow more than the mean of 6 or 7cm, and for a longer period than the ones who are later matures until they reach their final height.
